While there is currently no cure for type 2 diabetes, studies have shown that it is possible for some people to reverse the condition through diet and exercise. Reversing diabetes involves carefully managing blood sugar to a point where medication is no longer necessary, and this can be achieved through a healthy routine of diet and exercise. A combination of aerobic activity and strength training can help to lower blood sugar and reduce insulin resistance. In addition, a modest, lower-calorie diet can also help to put people on the path to remission.

What You'll Learn
Low-calorie diets can help reverse type 2 diabetes
Type 2 diabetes is a widespread health condition, affecting around 537 million people worldwide. While there is currently no cure, symptoms can be managed through medication and lifestyle changes.
The Link Between Type 2 Diabetes and Weight
Type 2 diabetes is primarily caused by weight gain associated with unhealthy diets, a lack of exercise, and/or a genetic predisposition to insulin resistance. When gaining weight, insulin goes into the fat tissue instead of the bloodstream, leading to insulin resistance. Therefore, addressing the underlying weight issues that led to diabetes can help reverse it.
Low-Calorie Diets and Type 2 Diabetes Remission
Several studies have found that low-calorie diets can help place type 2 diabetes into remission. A study by Weill Cornell Medicine-Qatar found that an intensive, one-year, lifestyle-modification treatment for type 2 diabetes patients, featuring a low-calorie diet and physical exercise, resulted in large average weight loss and remission of diabetes for most patients. About 61% of patients receiving the lifestyle intervention no longer had diabetes after the one-year trial, compared to just 12% in the standard care group.
Another study published in June 2021 found that people who followed an intermittent very-low-calorie diet achieved optimal glycemic control. Research presented at the Annual Meeting of the European Association for the Study of Diabetes in 2023 supported these findings, showing that a low-calorie diet led to lasting remission of type 2 diabetes.
The Importance of Exercise
While low-calorie diets can be effective, exercise is also crucial. A combination of aerobic activity and strength training can maximize weight loss and reduce insulin resistance. Muscles that are active and working can take in glucose more easily, helping to lower blood sugar levels.
Considerations and Challenges
While low-calorie diets have shown promise, they may not be suitable for everyone. Some studies have focused primarily on weight loss rather than diabetes remission, and long-term follow-up data is limited. Additionally, adhering to a low-calorie diet over an extended period can be challenging, and individuals without weight issues may not benefit from this approach.
In conclusion, while type 2 diabetes cannot be cured, low-calorie diets can play a significant role in placing the condition into remission for some individuals. However, it is important to consult with healthcare professionals before making any significant dietary changes, especially for those taking insulin or diabetes medications.

Intensive lifestyle interventions can lead to remission
A clinical trial conducted by researchers at Weill Cornell Medicine-Qatar found that an intensive, one-year, lifestyle-modification treatment resulted in significant weight loss and remission of diabetes for most patients. The intervention group followed a low-calorie diet and were encouraged to walk 10,000 steps per day and engage in at least 150 minutes of physical exercise per week. After one year, about 61% of these patients no longer had diabetes, compared to just 12% in the standard care group.
Several other studies have also shown that intensive lifestyle interventions can lead to remission. One study found that a very low-calorie diet of 625-850 calories per day for 2-5 months, followed by a less restrictive diet, resulted in nearly half of the participants reversing their diabetes and maintaining near-normal blood glucose levels for at least 6 months to a year. Another study showed that a combination of a modest, lower-calorie diet, increased physical activity, and a specific insulin and medication routine resulted in more than half of the participants achieving near-normal blood sugar levels without medication, with some maintaining these levels long-term.
The key to achieving remission through intensive lifestyle interventions appears to be weight loss. Dr. Shahrad Taheri, a professor of medicine, states that "if you lose weight early enough in the disease process, you can actually reverse the disease." This is supported by another study that found therapeutic fasting and a low-carbohydrate diet resulted in three participants with diabetes losing 10-18% of their body weight and stopping their diabetes medication, including insulin, within 1-3 weeks.
Intensive lifestyle interventions provide strong evidence that type 2 diabetes can be managed and even reversed through comprehensive lifestyle changes, particularly when implemented early in the disease process.

Exercise helps manage blood sugar levels
While there is no cure for type 2 diabetes, studies show that it is possible for some people to reverse it. Type 2 diabetes is often linked to weight gain associated with unhealthy diets, a lack of exercise, and/or a genetic predisposition to insulin resistance. Therefore, diabetes can be reversed through diet changes and weight loss, which can help people manage their blood sugar levels and live diabetes-free.
Exercise is a powerful tool for managing blood sugar levels in people with diabetes. Regular physical activity can lower blood glucose levels in the short term, and consistent exercise over time can lead to sustained improvements in blood sugar control. This is because muscles that are active and working are better able to absorb glucose from the blood and use it for energy. As a result, regular exercise can help prevent blood glucose levels from becoming too high or too low, reducing the risk of health issues associated with uncontrolled diabetes.
The positive effects of exercise on blood sugar levels can last up to 24 hours or more after a workout. The intensity and duration of physical activity can impact the extent of these benefits. For example, moderate-to-high-intensity cardiovascular exercises, such as brisk walking, jogging, swimming, and cycling, can significantly elevate the heart rate and improve blood sugar control. Additionally, combining aerobic activity with strength training can maximize weight loss and reduce insulin resistance, further enhancing blood sugar management.
The impact of exercise on blood glucose levels can vary between individuals, so it is important for people with diabetes to monitor their blood sugar levels before and after exercising. This allows them to understand how their bodies respond to different activities and adjust their exercise routines accordingly. By incorporating exercise into their regular routine, individuals with diabetes can effectively manage their blood sugar levels and improve their overall health.
In addition to exercise, dietary changes play a crucial role in managing blood sugar levels. Adopting a healthy diet that focuses on reducing sugar intake and overall calorie consumption can contribute to weight loss and improved blood sugar control. In some cases, therapeutic fasting or very low-calorie diets have been shown to help reverse type 2 diabetes and maintain near-normal blood glucose levels. However, it is important to note that such extreme diets should be undertaken with professional guidance and careful monitoring.

Weight loss is key to reversing diabetes
While diabetes has no cure, weight loss is key to reversing the condition. A combination of diet and exercise can help patients lose weight and manage blood sugar levels to the point where medication is no longer required.
Several studies have shown that a low-calorie diet and physical exercise can lead to weight loss and diabetes remission. In one study, patients on a low-calorie diet and exercise regimen lost an average of 26 pounds, compared to 9 pounds for those on standard medication-centred care. 61% of patients in the lifestyle intervention group no longer had diabetes after a year, compared to just 12% in the standard care group.
The key to reversing diabetes is early intervention. Patients who have only had the disease for a few years and have not yet needed insulin are more likely to achieve remission. One study found that patients who lost 30 pounds or more were able to reverse their type 2 diabetes and maintain near-normal blood sugar levels for at least six months to a year.
To achieve weight loss, a combination of diet and exercise is necessary. A modest, lower-calorie diet, combined with a step-up in burning calories through exercise, can lead to remission. Aiming for 10,000 steps a day and at least 2.5 hours of moderate exercise a week, along with cutting 500-750 calories a day, can lead to near-normal blood sugar levels without medication.
In addition to diet and exercise, other lifestyle changes can also help in reversing diabetes. These include not smoking, getting enough sleep, limiting alcohol intake, and managing stress. While it may not be possible to reverse type 2 diabetes for everyone, healthy lifestyle habits can help manage the condition and prevent complications.

Diabetes can be managed without medication
While diabetes has no cure, it can be managed without medication through diet and exercise.
A clinical trial led by Weill Cornell Medicine-Qatar researchers found that an intensive, one-year, lifestyle-modification treatment for type 2 diabetes patients resulted in large average weight loss and remission of diabetes for most patients. The treatment included a low-calorie diet and physical exercise. Patients in the lifestyle intervention group lost an average of 26 pounds, compared to the standard care group's average weight loss of 9 pounds. Furthermore, 61% of patients in the lifestyle intervention group no longer had diabetes after the trial, compared to just 12% in the standard care group.
Dr. Shahrad Taheri, a professor of medicine, emphasized that losing weight early in the disease process can reverse type 2 diabetes and prevent further health complications. While medication is often the standard care for diabetes, focusing on weight loss and lifestyle changes can be a more effective approach, especially for younger patients recently diagnosed.
Several studies support the idea that diabetes can be managed without medication. A study by UCLA Medical School found that addressing underlying weight issues through a healthy diet and regular exercise can help reverse diabetes. Another study by Northern Nevada Medical Center, Reno-Sparks, suggested that positive lifestyle changes, such as a well-balanced diet, regular exercise, maintaining a healthy weight, not smoking, getting enough sleep, limiting alcohol, and managing stress, can help manage type 2 diabetes.
In addition to these findings, a study by WebMD found that increasing physical activity and combining it with a lower-calorie diet can lead to remission. Participants in this study aimed for 10,000 steps per day, 2.5 hours of moderate exercise per week, and a reduction of 500-750 calories per day. More than half of the participants achieved near-normal blood sugar without medication, and some maintained these levels long-term.
While medication is a common treatment for diabetes, evidence suggests that lifestyle interventions, including diet and exercise, can effectively manage and even reverse the condition. These interventions can lead to weight loss, improved blood sugar control, and reduced health risks associated with diabetes.
